Which of the following is a key benefit of using biotechnology in agriculture?

One of the key benefits of using biotechnology in agriculture is the enhancement of crop yields through genetic modifications. This involves the alteration of specific genes in plants to improve traits such as growth rate, resistance to pests and diseases, and tolerance to environmental stresses like drought or salinity. By introducing beneficial traits into crops, biotechnology enables farmers to produce more food using the same or even fewer resources.

Enhanced crop yields can also lead to increased food security, allowing for a more efficient use of arable land and helping to meet the demands of a growing global population. Furthermore, improved crop traits may lead to reduced losses from pests and diseases, helping to stabilize and increase the overall productivity of agricultural systems.

While the other choices mention important agricultural concepts, they do not represent the primary benefit of biotechnology. For instance, reduction in labor costs may occur indirectly but is not the principal aim of biotechnology. Similarly, complete elimination of pesticide use is not realistic, as pest management remains a crucial aspect of agriculture. Increased reliance on traditional farming methods contrasts with the innovative approaches brought by biotechnology advancements. Thus, the enhancement of crop yields through genetic modifications stands out as the clear key benefit of utilizing biotechnology in agriculture.
